Preparation and performance study of a novel polymeric spraying dust suppression agent with enhanced wetting and coagulation properties for coal mine

In this work, an environmental friendly dust suppressant with improved wettability and coagulation properties was developed by a chemical modification method. The hydroxypropyl guar gum was synthesized by nucleophilic substitution reaction between natural polymer guar gum and propylene oxide . Through a series of optimization of adjuvant agents and viscosity experiments, the optimum formulation contained moisture agent W + 0.8% hydroxypropyl...
